COLMI R12 Smart Ring-Black,Rose Gold , Silver
Step into the next generation of discreet wearable technology with the COLMI R12 Smart Ring. Unlike traditional screenless smart rings that require checking your smartphone app to view stats, the R12 features a crisp integrated OLED digital display screen right on the ring’s outer surface. With simple smart touch gestures, you can cycle through the time, step count, active calories, heart rate, and battery status directly on your finger.
Crafted with a durable, skin-friendly inner shell and a sleek metallic outer finish, the COLMI R12 weighs just a few grams for non-intrusive all-day and all-night wear. Powered by low-energy Bluetooth 5.0, it continuously monitors your heart rate, blood oxygen (SpO2), stress levels, skin temperature, and multi-stage sleep quality. Accompanied by a portable charging case that doubles as a storage dock and power reservoir, it provides extended multi-day battery autonomy. Protected by an IP68 waterproof rating, it effortlessly handles handwashing, workouts, and swimming. Order yours today from Gadget99!
